Two cars collide at an icy intersection and stick together afterward. the first car has a mass of 1200 kg and was approaching at 6.00 m/s due south. the second car has a mass of 900 kg and was approaching at 24.0 m/s due west.
a. calculate the final velocity of the cars. (note that since both cars have an initial velocity, you cannot use the equations for conservation of momentum along the x-axis and y-axis; instead, you must look for other simplifying
magnitude incorrect: your answer is incorrect. m/s direction â° (counterclockwise from west is positive)
b. how much kinetic energy is lost in the collision? (this energy goes into deformation of the cars.)

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
